Should I keep my stock crx ecu plugged in? If not, what happens to the ground wires that run to the ecu that need to be grounded? Thanks

 

stock crx ecu does not stay plugged in, some of the ecu plugs will be part for the conversion harness you pretty much have to buy unless you are really good at wiring, i did not have to ground my ecu so not sure what you mean on that one, my k is running

 

Yea I have a Hybrid harness, but some of the stock ecu wires like A2 and A4 (main relay grounds (im sure you already know tho lol) in my mind should be grounded. Lol if yours works and you didn't leave the stock ecu plugged in then thats enough for me. One more question, does the stock rsx grey plug plug into the port on the far left or the far right of the ecu? Thanks
